Ultrasonic Testing

Training & Certification Course in NDT

We are providing Level I and Level II Training and Certification as per Recommended Practice SNT - TC-1A 2006 in the following NDT Method.

In Ultrasonic Testing high-frequency sound waves, created by a vibrated crystal in probe, are transmitted into a material to detect imperfections or to locate changes in material properties. The most commonly used ultrasonic testing technique is pulse echo, whereby sound is introduced into a test object and reflections (echoes) from internal imperfections or the part's geometrical surfaces are returned to a receiver

This method is very sensitive to detect crack type defects but requires extensive training for operator to interpret the result
